DRIVING MECHANISM.

To all who/n t may concern Be -it known that I, 'HARRY WV. BoLnNs, a citizen ot' the United States, and resident ot Port lVashington, in the county ot Ozaukee and State ot.' Wisconsin, have invented certain new and useful Improvements in Driving lt'eehanism; and I do hereby declare that the following is a l'ull, clear, and exact description thereof.

My invention has for `its object to provide simple, etliiective portable transmission gearing` and `traine therefor, 'its construction and ar `angement being such that power may be applied through a suitably supported connter-shatt to various machine elements in juxtaposition to which the .trame is temporarily located.

(lne specific object of my invention is to provide a skeleton traine for the support oit a counter-shaft, the frame comprising pa rallel looped struts each having an end rigidly secured to the base ot' an engine body with their opposite ends attached to the cylinder head otl such engine body, whereby a compact, rigid connection between the crank shaft and counter-shaft is eti'ccted, which counter-shaft is disposed rearward of the cylinder while the power or crank shaftt is located in the usual forward position rela tive thereto. The above arrangement o'lE supporting' :trame for the gearing thus 'forms a rigid tie between the drive and driven shafts whereby a tixed relation is maintained.

Another object ot my invention is to provide a counter-shaft that is rectangular in cross-section tor convenience in assembling various interchangeable sets of gearing ot either pulley or toothed gear type, the hub ot the gear-members being provided with rectangular bores to conform to the shaft whereby the same are in rotatable union therewith.

lVith the above objects in view my invention consists in what is herein shown, described and claimed.

In the drawings Figure l represents a plan view of an internal combustion engine provided with a gear transmission attachment embodying the features oit my invention, parts being broken away and parts in section to more clearly illustrate certain structural features; Fig. 2, a side elevation of the same with parts broken away and parts in section; Fig. 3, a cross-section of the engine, the section being indicated by line Specification of Letters Patent.

Serial No. 629,691.

:EMIS ot Fig. Q; Fig. 1-, a detail sectional view ot one ot the supporting bearings oi a eounter-shatt, aud Fig. 5, a detail plan view illustrating the counter-shaft equipped with a transmission gearing in the form of a series ot stepped pulleys that may be substituted il'or the toothed gearing illustrated in connection with the counter-shaft in Fig. l.

lie't'erring by characters to the drawings, 1 represents an engine base provided with tcct 2, S2', to which base is secured the cylinder 3 provided with upwardly extending walls Yt'orniing an open mouth water-cooling tanl; el. hlounted upon the base l is the usual crank-shaft 5 that is connected to a piston by a pitman 7. The crank-sllaft is also provided with a [1y-wheel S and a driving wheel f) in the torni ojt' a pulley. The engine cylinder 3 is also provided with a detachable cylinder head 3 carrying a standard valve mechanism 10 that is under cani control, not shown, the same being driven by a gearswhcel 11 from the crank- .sha'tft through a pinion 12 carried thereby. The above described engine is o't a well known type and 'terms no part of my invention, with the exception that the body thereot constitutes a part ot a portable frame that carries the transmission gearing.

The cylinder head 3 is provided with apertured ears 13 that extend laterally in either direction therefrom, to which ears are attached the downtllrned ends llt of upper stretches 14*l that form part of a pair of longitudinal struts, the downturned ends being secured to the ears l?) by Suitable bolts. The struts comprise one-piece parallel loops having vertically disposed .stretches 15 and bottom stretches 16 that extend under the tect of the engine base and are secured thereto by bolts 17. The vertical stretches 15 ot the struts are disposed rearwardly ot the engine cylinder and in the opposite direction to which power is applied to the crank-shaft. The struts are each preilerably bent up from a piece of U- shaped angle iron, their bottom stretches 1G being supported upon longitudinal skids 18.

The vertical stretch 15 of each strut is provided with a series of apertures 19 for the reception of retaining bolts 20 of a snpporting member 21 ot a two-part box. The eapmember 29 of each box is hinged to the supporting member and has a slotted flange 2? for engagement with one o'l the retaining boltsZO whereby said cap-member is secured. A counter-shaft 24 is journaled in the boxes, the same being rectangular in cross-section and provided with turned cylindrical sections 24 that are mounted within said boxes.

The counter-shaft, as shown in Figs. 1 and 2, carries a pulley 9 at one end that is in belt gear connection with the crank-shaft pulley 9, the said counter-shaft pulley being provided with a squared bore for engagement with the squared shaft end whereby said pulley is held in rotative engagement with the shaft. A-hanger 25 is provided with boxes at one end thereof that are journaled upon bushings 26 mounted upon the counter-shaft whereby said hanger is suspended thereabout, the bushings being provided with squared bores and adapted to rotate with the counter-shaft 24. The opposite end of the hanger carries a single box 27 into which is journaled an arbor 28 having a gear-wheel 29 secured to one end and a disk 30 secured to the opposite end thereof. The hanger-arbor is also rotatably mounted in journal bearings 31 of a bifurcated clip 32, the inner faces of which clip-bearings abut the opposite ends of the hangerb0x 27, whereby a hinged connection is formed aboutsaid arbor relative to the clip and hanger. The clip 82 has an apertured flange for the reception of retaining bolts 83 that engage a. saddle member 84, the same being provided for convenient attachment of the clip to a pump column or other machine element as indicated by dotted lines in Figs. 1 and 2. Both the gear wheel 29 and disk 30` carry crank-pins 29 for connection with suitable pitmen that may be linked to a pump-piston or other reciprocative mechanica-l element not shown.

The counter-shaft carries a toothed pinion 38 which imparts rotation to the gear-wheel 29 through an interposed idle pinion 39, the same being journaled upon a stud 40 that is carried by the hanger 25. The clip 32, gearwheel 29 and disk 30 with their various con nections constitute a pump-jack comprising one mea-ns whereby the engine can be readily coupled to a pump or other mechanical ele-v ment to which reciprocative power is to be applied, and, as previously stated, the hanger 2,5 being in hinge connection with the counter-shaft and arbor, this movement permits ample scope for vertical adjustment as to elevation of t-he gearing.

The split journal-boxes of the countershaft may be adjusted to various elevations and secured in their adjusted position by the retaining bolts 2O that are fitted into any one of the separate sets `"of strut apertures.

The idle pinion 39 through which power is transmitted from the power shaft to the gear-wheel 29 is inserted for the purpose Y -of overcoming the reverse drive of the said gear-wheel which would otherwise occur Vshould the same be directly meshed with that any suitable form of gearing other than that shown may be employed to transmit power from the counter-shaft to the crankshaft and from thence to the machine element.

Uien it is desired to supplement the toothed driving gear illustrated in Figs. 1 and 2 for a belt drive, the squared countershaft is removed from its journal-boxes and stripped of the hanger 25 and its gear connections. As shown in Fig. 5, the countershaft is then equipped with ra series of stepped pulleys 41, the hubs of which are provided with squared bores whereby they may be quickly assembled in ltheir respective order and are thus rendered capable of being rotated with the shaft without resorting to keys or other securing means, this change of gear being readilyreiiected by those unskilled in the art of mechanics by simply sliding the pulley or driving meinbers into position. After the pulleys are assembled the shaft can be dropped into the split boxes and secured in the manner previously described, there being a clutch pulley 42 connected to one end of the countershaft whereby rotatory power therefrom may be transmitted to a separator Vor any machine element Vrequiring power in a continuous rotary form.

A convenient means for attaching the fuel tank 48 is illustrated in Figs. 2 and 3 of the drawings, which means comprises a transversely disposed strap 44, the ends of which are interposed between the engine base feet 2 and the stretches 16 of the struts upon which strap the tank is supported. The ends of a second transversely disposed strap 45 are also nested over the first mentioned straps and interposed between the engine base feet and strut stretches 16. This strap is in the form of an inverted U and extends over the top of the tank whereby the same is securely held in position between the engine base feet 2 which straddle the same as best shown in Fig. 3. The tank is connected bv a suitable feed-pipe 43 to the carbureter 43". The ends of the straps 44 and 45 are secured by the bolts 17 which pass therethrough, but it isl understood that, in some instances, the said ends may be held by a frictional grip between the engine basev thereof, a squared counter-shaft journaled,

at the opposite end .of the frame, gear mem- Vbers having squared bored hubs fitted to the counter-shaft, a driving connection betWeen one of said gear-members and drive-shaft, bushings fitted to said Counter-shaft, a hanger journaled upon the bushings, and a gear-train carried by the hanger, one of its members being in meshed engagement with one of the eountersshai't gear members.

2. A transmission mechanism comprising a fran'ie, a drive-shaft mounted in one end thereof, a squared counter-shaft journaied at the opposite end of the iframe, gear members having squared bored hubs fitted to the counter-shaft, a driving connection between one of said gear members and drive-shaft, bushings fitted to said counter-shaft, a hanger journaled upon the bushings, a geartrain carried by the hanger having one ot' its members in mesh with one of the countershaft gear members, and means in connection with the free end of the hanger for attachment to a fixed machine element.

3. A transmission mechanism comprising a frame, a drive-shaft journaled at one end of the frame, a squared counter-shaft journaled at the opposite end of said frame, the said eounter-shaft being in beit gear connectio-n with the drive shaft, a hanger loosely mounted upon the eounter-sbaitt, a gear member having a squared bored hub fitted to said counter-shaft, and other gear means carried by the hanger in driving engagement with the squared shaft gear member.

lf. A transmission mechanism comprising a frame, a squared shaft ournaled therein, a gear member having a squared bored hub mounted upon the shaft, a hanger provided with boxes that engage the shaft, a box carried by said hanger at its opposite end, an arbor mounted in the box, a bifurcated clip mounted about the arbor, means for attach ing the clip to a machine element, and a gear train carried by the hanger, one gear of the train being in driving connection with the squared shaft gear member.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the eounty of Milwaukee and State of Wis eonsn in the presence of two witnesses.
